HAIR WAVING AND CUBLING APPARATUS.

Specification of Letters Patent. PatentedNav. 14, 1916.

Anplication filed April 18, 1918. Serial No. 90,888.

To all whom it may concern: r Be it known that we, HANNAH JAooBs and HARRY JACOBS, citizens of the United States, and residents of New York, in the county of Kingsand State of New York, have invented certain new and useful Improvements in Hair Waving and'Curling Apparatus, of which: the followingis a specification.

This invention relates to improvements in hair waving or curling appliances, in which the strands of the hair" of the head are" wound and twisted upon a, stem in the usual way but in which theheating element is water which has been heated to itsmaximum temperature or to the boiling point. Heretofore all deviccs of this character have employed an electrical means for heating, which devices necessarily must be operated by those skilled in their manipulation. A

' flowof electrical current through the device which may be of too long duration may overheat the hair with very serious consequences. In order to obviate this ossibility and objection we have devise an apparatus with a heating element WlllCll provides a maximum heat which W111 not We further rovide a means for maintaining this heat or a prolonged period. \Ve attain "these objects by the device illustrated in the accompanying drawings which shows an apparatus of simple construction and which will be economical in cost of manufacture and in operation or use.

Referring to the drawings Figure 1 is a longitudinal section through the device with the parts all assembled and ready for use and indicates, by dotted lines, the relative position of the piping or winding stem; Fig. 2 is a sectional View of the hot water container-which willbe hereinafter fully described; Fig. 3 is a sectional view of the two parts forming the containerfor. the vacuum insulating member, and Fig. .l': is

sectional view of the said vacuum insulating member whose function will be hereafter fully' described' Similar letters refer to similar parts throu hout.

'Rei erring to the parts 1 is a hot-water recs tacle constructed of any suitable heat condilcting metal and having an opening 2 with cap 3 therefor. The said cap 3 having a; resilient; washer 4 to insure a tight joint when cap is screwed down; Tothe base 5 v The suspendin' .of the said receptacle 1 there is secured a non-metallic cupped secondary base 6 having the annular flanges ,7, and made of heat insulating-material such as fiber or asbestos composition and attached to said secondary base 6 there is a backing of a spongy absorbent material 8. The hot water receptacle 1 is formed with a central chamber 9in which the piping or winding stem 9 (shown by dotted lines) is adapted to engage.

A jacket composed of an inner and outer shell 10 and 11' respectively is adapted to contain, within its walls, a vacuum insulating member 12 which member engages around the inner shell 10 against the Hat springs 13 formed upon the cupped base 1%. The said base 1d is provided with an inner threaded annular ledge 15 which engages the threaded edge of the outer shell 11 when the said outer shell 11 -engages around the said vacuum insulating member -12. The annular ledge 15 is provided with pins or lugs 16 which are adapted to eng'a e slots or recesses 17 in annular ledge 7 or the purpose of holding all the parts together. The insulating member 12 is preferably made of glass and is a Yesselshaped as shown with a double wall. The air in the space 17 between the double walls is exhausted by any approved method and the vessel sealed in the usual way as at 18.

To protect the vacuum member 12 from possible breakage by contact, the outer shell 11 is provided with a lining 19 of soft 'fabric and a cushion 20 of any suitable material. suspending rings 21 are provided upon the shell 11 by means'of which recesses 17. -The whole is tlen passed over the stem-having the hair wound upon it. rings 21 are attached to lot suitable suspen ing means. The heat from the water in the container 1 is transmitted the desired result. The jacket containing th vacuum insulating member 12 prevents the absorption of any of the heat from the container 1 thereby insuring the maxi um amount of heat for absorption by the h ir. Thewater to be used may be heated by any suitableiiieans before it is placed within the containerl or it may be heated while in I the said container by placing same upon any suitable neating device.

Ifi Fig. 2, we show by means of dots 22, an electrical 'resistance element which con sists of an asbestos covered coil of wire through which an electrical current is passed and contained until the water is heated to the desired temperature. conductors maybe led out through the base 6 of the container 1. When the electric cu'rrent is-used the insulator jacket may be dispensed with and the current continued as long as the heat is applied to the hair or the current may be out off after adefinite time and the insulating jacket applied.

In the drawings we show avacuum insulatin member, we do not claim this feature: broadly asour invention, we showthis con-' struction as thepreferable means of insula tion in conjunction with our device; An insulating jacket however', of any heat-insulating materialmay be employed.

It is o vious that we may embody various modifica ions without departing from the spirit 0 our invention, we do not therefore 7 wish to be understood as limiting ourselves to the articular construction shown.

Wh t we do wish to secure by Letters Pate is:

'1. n a hair waving and curling apparatus a double walled liquid containing metaliic heating member adapted to engage a winding stem having hair curled dr wound The ends of the thereon, a threaded neck or opening formed upon one end of said heatin member and adapted for filling said heating member, a threaded cap adapted to engage within the said neck to closesame, a double walled cylindrically formed outer casing, open at one' end and adapted to detachably engage with the said heatlng member,and a heat-msulating member interposed between the said heating member and'said outercasing'and held within the walls of 'the said outer casing.

2. In a hair waving and curling appara- "tus, a double walled liqui; containing mewithin the walls of the said outer casing and'a heat insulating-'ring secured to one end of the said heating member and adapted to protect theuser against the heat fromthe sa1d heating member.
